    Modbus/TCP on FENA-01 Ethernet Adapter Module The FENA-01 Ethernet Adapter module is an optional device for ABB drives which enables the connection of the drive to an Ethernet network. The module supports a variety of higher-level communications protocols, including Modbus/TCP.

  • Page 12: Compatibility

    • read status information and actual values from the drive • change drive parameter values • reset a drive fault. The FENA-01 acts as a Modbus/TCP server with support for ABB Drives and Transparent profiles. The Modbus commands supported by the FENA-01 Ethernet Adapter module are discussed in chapter Communication.

  • Page 13: Drive Configuration

    Normally, a parameter must be adjusted to activate the communication (see the drive documentation). As communication between the drive and the FENA-01 is established, several configuration parameters are copied to the drive. These parameters (Table Table 2.

A subnet mask is a 32-bit binary number that is used to split the IP Address into a network address and host address. Subnet masks are typically represented in either dotted-decimal notation or the more compact CIDR notation.

  • Page 23: Control Locations

    ABB drives can receive control information from multiple sources including digital inputs, analogue inputs, the drive control panel and a communication module (eg, FENA-01). ABB drives allow the user to separately determine the source for each type of control information (Start, Stop, Direction, Reference, Fault Reset, etc.).

    ABB drives can receive control information from multiple sources including analogue and digital inputs, the drive control panel and a communication module (eg, FENA-01). In order to have the drive controlled through the fieldbus, the module must be defined as the source for control information, eg, Reference.
